GAS-GENERATOR.

SPECIFICATION forming part of Letters :Patent No. 757,615, dated April 19, 1904.

Application leu September 28, 1903. Serial No. 174.938.- (No model.)

vTo all whom t may oon/cern,.-

Be it known that I, HANS C. HANsoN, a citi? Zen of the United Statearesiding at Albert Lea, in the State of Minnesota, have invented certain new and useful Improvements in Gas- Generators; and I do declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilledV in the art to which it appertains to make and use the same. i

` of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claim, reference being had vto the accompanying drawings, in which- Figure 1 is a perspective view ofV a gas-generator embodying my invention. Fig. 2 is a vertical longitudinal section of the same, and Fig. 3 is a cross-section on line 3 3 of Fig. 2.

In the embodiment of my invention as shown, 1 denotes a feed-valve, to the casing oi' which a hydrocarbon-supply pipe (not shown) leading from a tank or reservoir is to be connected. This valve is disposed upon the base of an upright generator 2, which consists of a tube containing an absorbent packing of gravel or other suitable heatconducting material. At its upper end this generator carries avaporizing-burner 3, over which is arranged a deiecting andheat-aocumulating plate 4. The. purpose of this plate 4 is to concentrate the heat upon the top portion of the generator, and thereby secure the effective conversion ofthe hydrocarbon passing through the tube 2 into gas. The upper end of the generator has an offstanding arm 5, in which is a gas-passage, and the outer upwardly-extending portion of this arm the gas to the burners or polnts of consump- 6oV tion.

The vaporizing-burner Sis supplied with gas through a vertical pipe 11, leading downwardly from the service-pipe 10 and connected at its lower end, to a horizontal or 6 5 cross pipe 12, which is connected at one end to the burner 3 and at the opposite endto the pressurefregulator 13. In the pipe 3 is a valve 14, by which the supply of gas to the burner 3 may be controlled;

Y The pressure-regulator 13g-comprises a watercontaining tank 15, open at top to receive a bell or float 16, which raises and lowers under the pressure of the gas. y, This bell or iioat is pivotally connected to one end of alever 17, which is ulcrumed at 18 to a bracket extending from the plate 4 and is providedat its outer or free end with a counterweight 19, adjustably secured thereto by a set-screw 20.

Pivotally connected to the lever 17 is a rod 8O 21, which projects upwardly into the air-inlet tube 8 and terminates therein in a downwardlyextending needle-valve 22. This valve controls the port 23 in the upper end of the pipe the service-pipe and burners.

In the operation of the device the generator 2 after being preliminarily heated starts the generation of gas, and this gas flows upward .6, and thereby regulates the supply ot gas to into the mixing-tube 7, where it is commingled with air entering through the air-inlet`8, and thence feeds into the service-pipe 10.- A portion of the gas iiows down from the service-pipe through the pipe 11 and is divided by the pipe 14, a part passing to the burner 3 95 and a part to the pressure-regulator 13. The gas supplied to the burner 3 is ignited, and the burner is kept in constant operation to heat the generator 2 for the continuous generatie of gas. That portionof the gas entering the IOO regulator 13 acts upon the bell or iioat 16, according to its force or pressure, and when the pressure is too high closes the needle-valve to reduce or cut off the supply of gas to the burners or if the pressure is too low opens the valve and allows more gas t0 iiow to the burners. When the pressure of gas is too strong, the weight 19 is adjusted farther out on the free end of the lever, and when the pressure is insuflcent it is adjusted farther inward toward the fulcrum-point, as will be readily understood. By

vthis invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a gas-generator, the combination of an upright generator provided at its upper end with a burner and a deiecting-plate above above the mixing-chamber and adapted to receive the commingled vapor and air therefrom, a pressure-regulator arranged at one side of the generator and having a movable element operated by gas-pressure, a pipe leading therefrom to the vaporiZing-burner, a pipe leading from said pipe to the service-pipe to supply the vaporizing-burner and generator with gas from said servicepipe, a needlevalve adapted t0 be operated to close the jetoutlet'upon an excess of pressure in the'service-pipe, and a lever fulcrumed to the generator and connected on opposite sides of its fulcrum to the valve and Inbvable element of the pressure regulator, and adapted to be rocked by said regulator to operate the valve to open or close the jet-outlet, substantially as described.

In testimony whereof I have hereunto'set Amy hand in presence of two subscribing wit- IIGSSGS.

HANS C. HANsoN.
